Start with reversible changes. Lower the in-game options that your title identifies as performance-heavy, change one setting at a time, and compare the same repeatable scene. Keep GPU clocks and voltage at their defaults until those changes are tested. Use a frame cap or variable-refresh feature to improve frame pacing and prevent tearing when appropriate; those controls change how frames are displayed, not how many the GPU can render. Treat overclocking and undervolting as optional experiments that require deliberate stability testing.
What “better FPS” can mean
Frame rate, smoothness and input latency are related but different outcomes. A lower quality setting can let the GPU render more frames per second. A frame cap can deliberately lower the peak while making frame delivery more even. V-Sync and variable refresh rate (VRR) can remove visible tearing without increasing rendered FPS. Before changing anything, decide which problem you are solving.

- Raw FPS: the number of frames the game renders. This improves when the GPU is the bottleneck and a demanding workload is reduced.
- Frame pacing: how evenly frames arrive. Uneven frame times can feel stuttery even when the average FPS looks high.
- Input latency: the delay between an action and the resulting image. Sync modes and queue behavior can change this independently of average FPS.
- Tearing: parts of multiple frames appearing at once. A cap, V-Sync or VRR can address it, but none guarantees more rendered frames.
There is no universal percentage or number of extra frames that applies to every GPU and game. The gain from a setting depends on the title, resolution, scene and graphics card.
Build a reliable baseline before changing settings
A baseline prevents you from mistaking a different scene or a random frame-rate swing for an improvement.

- Choose a repeatable scene. Use the same benchmark, replay segment, training area or save point every time. Record the map, camera position and approximate test duration.
- Write down the current configuration. Note resolution, display mode, quality preset, individual graphics options, synchronization mode and any cap. Record the GPU driver version if you know it.
- Measure more than the average. Capture average FPS and, when your overlay provides it, 1% lows or frame-time data. A higher average with much worse lows may feel less stable.
- Change one variable. Do not lower several options and enable an overclock in the same test. You will not know which change helped or caused a problem.
- Repeat after each change. Return to the same scene and allow the game to reach its normal workload before recording results. Keep notes so you can restore the best known configuration.
If your test is not repeatable, use observations over several runs rather than treating one unusually high or low reading as a result.
Lower demanding in-game settings first
NVIDIA’s latency guidance recommends reducing game settings to improve performance. AMD likewise notes that limiting tessellation can improve FPS in games that use high tessellation. These are recommendations to test, not a universal order that works for every title.
Find the settings that are actually expensive
Start with the options the game labels as performance-heavy, or with an in-game benchmark that identifies a particular effect. Test effects and quality levels individually. If lowering an option produces no measurable change, restore it and try another; it may not be the bottleneck in your scene.
- Tessellation: On AMD-supported settings, reducing tessellation can help in titles that use high levels. The visual impact varies by game, so inspect surfaces and geometry after changing it.
- Other quality options: Shadow, lighting, volumetric, reflection and post-processing controls can have very different costs from one engine to another. Use the game’s own performance indicator or benchmark when available, then verify with your repeatable scene.
- Presets: A lower preset is a quick diagnostic. Once you confirm that quality is the bottleneck, raise individual options until you reach the image quality you want.
Keep native resolution if image sharpness is your priority. The available guidance does not establish a universal resolution setting or a stable FPS gain for lowering it. If you choose a lower resolution or a resolution scale, record that image-quality tradeoff alongside the measured result.

Use a frame cap to control excess rendering
When a game regularly renders above your display’s refresh rate, AMD recommends testing either an in-game frame cap or V-Sync for a tear-free experience. A cap can also keep the GPU inside a display’s VRR operating range. It does not create additional performance; it intentionally limits the maximum.
When a cap is useful
- Your GPU is rendering far above the panel’s refresh rate and producing tearing.
- Frame rate repeatedly moves in and out of the supported VRR range.
- You prefer lower power, heat or fan noise over an uncapped peak.
- You want a consistent frame-time target for a competitive or cinematic experience.
How to test it
- Use the game’s Graphics, Display or Video menu and set an in-game cap.
- Choose a limit that matches your display’s refresh behavior and your VRR range, if you use VRR. The sources do not establish one universal offset or number, so test the value with your own panel.
- Replay the baseline scene. Check for steadier frame times, tearing and control response, not only the displayed FPS.
- If the cap causes an unwanted responsiveness tradeoff, remove it and test another synchronization method instead.
Choose the right synchronization method
V-Sync, Adaptive V-Sync, FreeSync and G-SYNC solve frame-presentation problems in different ways. Compatibility, refresh range and latency preferences determine which is appropriate.
| Option | What it changes | Potential benefit | Tradeoff or requirement |
|---|---|---|---|
| V-Sync | Synchronizes presentation to the display refresh. | Can reduce or eliminate visible tearing. | Conventional behavior can stutter when FPS falls below the synchronization rate; exact behavior depends on the game and implementation. |
| Adaptive V-Sync | NVIDIA’s mode changes V-Sync behavior as frame rate moves around the display limit. | Can reduce tearing at high FPS while avoiding some low-FPS stutter. | Behavior and latency depend on the game, driver and display; it is not a raw-FPS boost. |
| FreeSync | Uses a compatible display’s variable refresh capability to follow GPU frame output. | Can reduce tearing and stutter across the panel’s supported range. | Requires a FreeSync-compatible display and GPU, with the feature enabled in the display and driver. |
| G-SYNC | Matches a compatible display’s refresh to the GPU frame rate over its supported range. | Can smooth output and reduce tearing when correctly configured. | Requires a G-SYNC or G-SYNC Compatible display and compatible configuration. |
| Frame cap | Stops the game from rendering above a chosen limit. | Can keep output within a VRR range and avoid needless rendering. | Peak FPS is reduced by design; the best limit depends on the display and the player’s responsiveness preference. |
Enable only the combination you intend to test, then use the same scene and overlay. A synchronization setting that removes tearing may still leave a GPU-bound scene at the same underlying FPS.
Set up VRR only when the hardware supports it
VRR is a display feature, not an FPS multiplier. It changes the display’s refresh timing to follow the GPU within a supported range. AMD advises enabling FreeSync in both the display and the driver. NVIDIA states that G-SYNC requires a G-SYNC or G-SYNC Compatible display.

- Turn on the monitor’s FreeSync, G-SYNC or equivalent setting in its on-screen menu.
- Enable the corresponding feature in the graphics driver. The exact label and available controls vary by GPU, driver and display.
- Launch a game and verify that the feature reports as active. If the display leaves its supported range, test an in-game cap or the game’s V-Sync option.
If your display has no compatible VRR support, a frame cap or V-Sync can still address tearing, but neither will provide the adaptive-refresh behavior of VRR.
Consider undervolting or overclocking only after software changes
Clock and voltage tuning can change performance or efficiency, but no guaranteed gain or universal stable setting is established. Keep these experiments separate from graphics-quality changes so that failures are diagnosable.
Undervolting
AMD Software: Adrenalin Edition documents an automatic undervolt option that reduces voltage while maintaining clock speeds, with the goal of improving performance per watt. Availability depends on the GPU and software version. “Automatic” does not mean universally stable: validate the result in the games you actually play.

Overclock controls can raise performance when the card and cooling system have headroom, but the result varies by individual hardware. Increase one control gradually, save the default values, and test after every change. A setting that passes a short test can still fail in a particular game.

Use the vendor’s safety behavior
AMD documents a GPU stress test in AMD Software. Its documented behavior is specific to that software: if the test causes a crash or reboot, AMD Software resets tuning settings to defaults. Do not assume another vendor’s tool behaves the same way. If you see artifacts, driver resets, freezes or reboots, revert to the last known-good values immediately.
A stability-testing and recovery checklist
- Save defaults: Record stock clock, voltage, power and fan values before tuning.
- Change one control: Alter only one frequency, voltage or power setting per test.
- Run a stress test: Use the test supplied by your GPU software when available, then play a demanding section of your usual game.
- Watch for subtle failures: Sparkles, flashing textures, geometry errors, black screens, driver restarts and application exits are instability even if the benchmark finishes.
- Revert, do not stack failures: Return to the last stable value before trying another adjustment.
- Check after driver or game updates: A previously stable tune may need to be retested after software changes.
For a system that must remain dependable, stock settings are the correct endpoint. A small theoretical gain is not worthwhile if it causes crashes during long sessions or corrupts unsaved progress.
Practical profiles for different priorities
| Priority | Recommended starting point | What to monitor |
|---|---|---|
| Maximum image quality with fewer crashes | Keep native resolution and default GPU clocks; lower only the game options proven to be bottlenecks. | Average FPS, 1% lows or frame times, visual quality and crash-free sessions. |
| Smooth presentation | Use a compatible VRR mode, then test an in-game cap if FPS exceeds the display range. | Range coverage, tearing, frame-time consistency and input response. |
| Lowest power and noise | Cap FPS to the target you can sustain; consider a conservative, validated undervolt. | Temperatures, fan behavior, clock stability and game-specific errors. |
| Competitive responsiveness | Measure latency and frame times with conservative quality reductions; compare cap, V-Sync and VRR combinations rather than assuming one is best. | Control response, consistency during heavy scenes and any tearing you can tolerate. |
Common mistakes that make a tune look better than it is
Changing several settings at once
A new preset, lower resolution and an overclock can produce a higher number, but you cannot identify the cause or reproduce it safely. Roll back and test each variable separately.

Confusing a cap with an FPS increase
An overlay may show a lower but steadier number after a cap. That can improve pacing or reduce tearing, yet the GPU is not rendering more frames.
Assuming a vendor setting works on every card
AMD’s tuning controls, stress-test reset behavior and legacy Radeon options depend on supported GPU and software combinations. NVIDIA’s G-SYNC requirements depend on display compatibility. Check current documentation for your exact model and driver before applying a control.
Keeping an unstable setting because it “usually works”
Intermittent driver resets and visual artifacts are failures. Restore defaults or the last stable profile; do not wait for a crash to confirm what the symptoms already show.

A safe decision order
- Measure a baseline in a repeatable scene.
- Lower one demanding in-game option and measure again.
- Keep native resolution unless you accept the image-quality cost of changing it.
- If FPS exceeds the display refresh, test a cap or V-Sync for tear control.
- If both devices support VRR, enable the matching FreeSync or G-SYNC feature and verify it.
- Only then test a conservative undervolt or overclock, one change at a time, with stability checks and an easy path back to defaults.
This order prioritizes changes that are reversible and easy to attribute. It also keeps the distinction clear: quality reductions target rendered FPS, while caps and synchronization target presentation, pacing and latency.
